“…However, a serious problem exists when RL is used in multi-agent systems is that the explosion of state space (curse of dimension). To overcome this hurdle, approaches using fuzzy inference systems (Jouffe, 1998), (Wang, X. S., et al, 2007), adaptive global radial basis function (GRBF) network (Samejima and Omori, 1999) are proposed, and recently classifying states using ART (Kobayashi et al, 2005), Neuro-GAS-like technique or hierarchical structure model (Wang, B. N. et al, 2007) are also given effectively. In this study, individuals are assumed without any knowledge of the environment, and they act according to a stochastic policy of the internal model temporally.…”
